xfs: pass bmalloca to xfs_bmap_add_extent_hole_real
All the parameters passed to xfs_bmap_add_extent_hole_real() are in the xfs_bmalloca structure now. Just pass the bmalloca parameter to the function instead of 8 separate parameters. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Alex Elder <aelder@sgi.com>
